"The World Food Programme (WFP) lost six staff, the Office of the High Commissioner on Refugees (UNHCR) lost two, as did the International Telecommunications Union (ITU). The Food and Agriculture Organization (FAO), International Organization for Migration (IOM) in South Sudan, World Bank and UN Assistance Mission in Somalia (UNSOM) each lost one staff member. Six staff from the UN Office in Nairobi (UNON) were also tragically killed," the statement read.

One of those who tragically lost their lives was UN animal campaigner Joanna Toole. The young British national was on her way to hold workshops with local fisherman as part of her role.

David Beasley, the Director of the WFP, who lost six staff members in the crash said those who were killed should be remembered for their willingness to leave their homes and loved ones behind to "help make the world a better place to live".

The UN and all its agencies will be flying their flags at half-mast as a mark of respect for those who lost their lives.
